Power

The power while dieting tends to decrease, but if you optimize your weigh training program (appropriate volume,frequency and intensity) the power will barely go down......if will. I personally note a cc 3-5% decrease. This year example:

ATG Squat: (I do not know for the low bar squat, because I didn't do it a lot in offseason, few weeks ago I did it 2 x 140 kg)
-offseason 3 x 125 kg
-3 weeks out 3 x 120 kg

Bench press (poor bench this year)
-offseason 3x3x107 kg
-3 weeks out 3x3x105 kg

Sumo deadlift:
-No difference - I rarely go to 100% in this lift, even in the offseason, I pulled 2 x 200kg few weeks ago, similar weight I pulled in winter

In other assistance work, I do not notice much change in weights....I do better the chin-ups now, because I weight 7-8 kg less, that's sure:))

The most important thing to look after in training on a diet is the total volume (expecially in the power / volume days and in compound movements)and to listen very carefully to your body. Don't be a fool, and do things like 15-20 repetitions every workout, short rest periods,......The golden rule is: what makes the best for muscle growth, will do the best to maintain em' !!

My weight dropdown from april, my max weight this year was around 83 kg @ 8-10% bf
